What is an intra-ocular lens?
An IOL (intra-ocular lens) is the substitute for the natural lens to maintain the vision without thick glasses. After a cataract surgery an IOL implant is a routine step. Most common implants are placed ‘in the bag’ which is considered the safest implant site. There are other sites for the lens implant but they are chosen only if an ‘in the bag’ implant is not possible. What is an after cataract? A posterior capsular opacity is an opacity that can form behind an intra-ocular lens implant after cataract surgery. The opacity develops in the posterior capsule (posterior part of the clear membranous bag) that supports the lens implant after cataract surgery. After a successful cataract surgery, it may take several weeks to several years to develop an after cataract. It is not necessarily the case that all will have an after cataract. Other names for this condition include secondary cataract, posterior capsular membrane, or posterior capsular fibrosis. Why does an after cataract develop? Th
